New strings in Orca.

[Rich Burridge <Rich Burridge Sun COM>]

Hi,

In order to fix Orca bug #364518 – Create a GUI interface to the
pronunciation dictionary, I've had to add some new strings that will
need localizing.

In .../orca/src/orca/orca-setup.glade:

Pronunciation Dictionary
_Add
_Delete
Pronunciation

In .../orca/src/orca/orca_gui_prefs.py:

Actual String
Replacement String

There are detailed translators comments for these last two.

These changes have been checked into Orca SVN HEAD and will
be part of the Orca 2.19.6 tarball next Monday.

Thanks.
